US: Stocks end at records for 2nd day on Trump tax cut promise

All three major indices finished at new highs for the second straight day, with the Dow Jones Industrial Average winning 0.5 per cent to end at 20,269.37.

The broad-based S&P 500 gained 0.4 per cent at 2,316.10, while the tech-rich Nasdaq Composite Index climbed 0.3 per cent to 5,734.13.

Gregori Volokhine, president of Meeschaert Capital Markets, attributed the gains directly to Mr Trump's statement Thursday that he would release details of a "phenomenal" tax-cut plan in two to three weeks - a statement he echoed on Friday.

Ford rose 1.1 per cent after announcing it would invest US$1 billion in an artificial intelligence startup Argo AI, part of a goal of releasing an autonomous vehicle for commercial use by 2021.

Video game developer Activision Blizzard surged 18.9 per cent after announcing it raised its dividend and approved a new US$1 billion in share repurchases. Those moves followed better-than-expected fourth-quarter earnings due to solid sales during the holiday season.

Electronic Arts, another video game developer, rose 3.5 per cent.

Sears Holding soared 25.6 per cent as it announced it planned cost cuts of at least US$1 billion annually. The retailer expects to close 150 stores during the first quarter.
